Technologies for dynamic generation of a media compilation

ABSTRACT

Technologies for generating a media compilation include comparing video metadata associated with a video to audio metadata associated with a plurality of digital songs to determine one or more matches between the compared metadata. The metadata defines various characteristics of the corresponding video and digital songs, and each match is indicative of a similar characteristic of the video and a corresponding digital song. One or more sync points are generated based on the determined matches and one or more songs are selected based on the sync points. The sync points may be prioritized based on the characteristics associated with the sync point and/or the degree of similarity. The video and the selected digital song(s) are subsequently compiled based on the associated sync points.

BACKGROUND

Media compilations include video and associated audio. In professionally produced media compilations, the audio of the media compilation is often synced with the video (e.g., similar tempo or speed). Oftentimes, such professionally produced media compilations require a professional to manually sync the audio and video by manually adjusting or modifying either or both media such that two media match each other. Such manual syncing can be time intensive and difficult.

With the ever increasing power of personal and desktop computers, typical users are creating media content at an ever increasing rate. For example, many users like to create media compilations from personal or home video by attaching one or more songs to the home video. However, because the typical user is not a professional, the creation of the media compilation can be overly complicated. For example, the typical user may not know how to sync a song to the home video and/or select suitable songs for the particular video.

Referring now to FIG. 1, an illustrative system 100 for generating a media compilation includes a compute device 102, which may be configured to communicate with one or more mobile compute devices 104 over a network 106. In use, the compute device 102 is configured to generate a media compilation of a selected video and audio available to the compute device 102. Illustratively, the audio includes, or is embodied as, one or more digital songs, but may include other audio data in other embodiments. To generate the media compilation of the selected video and audio, the compute device 102 compares video metadata associated with the video and audio metadata associated with each digital song to determine whether any of the metadata matches. If a match is found between the two metadata, the compute device 102 generates a sync point for the particular match. As discussed in more detail below, the metadata may be embodied as one or more metadata tags, each of which is indicative of a different characteristic of the associated video or digital song. As such, each sync point is indicative of a matching characteristic between the video and the corresponding digital song. In some embodiments, the compute device 102 is configured to prioritize the generated sync points. For example, the compute device 102 may apply a weighting factor to each sync point based on a correlation policy, which may define a weighting factor for various matching characteristics. The compute device 102 may subsequently select one or more digital songs to be compiled with the video based on the sync points (e.g., based on the weighting factor associated with each sync point). The compute device 102 compiles the video and the selected song(s) to generate a media compilation. In so doing, the compute device 102 may sync the selected song(s) to the video based on one or more of the generated sync points between the video and selected song(s). Additionally, in some embodiments, the compute device 102 may modify or adjust the selected song(s) to fit or better sync with the video. In this way, the compute device 102 is configured to generate a media compilation of media owned by the user with little or no direction from the user.

The compute device 102 may be embodied as any type of computer or compute device capable of performing the functions described herein. For example, the compute device 102 may be embodied as a desktop computer, a tablet computer, a smartphone, a laptop computer, a notebook, a netbook, an Ultrabook™, a smart device, a personal digital assistant, a mobile Internet device, and/or other compute device. As shown in FIG. 1, the illustrative compute device 102 includes a processor 110, an input/output (“I/O”) subsystem 112, a memory 114, a data storage 120, a communication circuit 122, and one or more output devices 124. Of course, the compute device 102 may include other or additional components, such as those commonly found in a typical computing device (e.g., various input/output devices and/or other components), in other embodiments. Additionally, in some embodiments, one or more of the illustrative components may be incorporated in, or otherwise form a portion of, another component. For example, the memory 114, or portions thereof, may be incorporated in the processor 110 in some embodiments.

The processor 110 may be embodied as any type of processor capable of performing the functions described herein. For example, the processor 110 may be embodied as a single or multi-core processor(s), digital signal processor, microcontroller, or other processor or processing/controlling circuit. Similarly, the memory 114 may be embodied as any type of volatile or non-volatile memory or data storage capable of performing the functions described herein. In operation, the memory 114 may store various data and software used during operation of the compute device 102 such as operating systems, applications, programs, libraries, and drivers. The memory 114 is communicatively coupled to the processor 110 via the I/O subsystem 112, which may be embodied as circuitry and/or components to facilitate input/output operations with the processor 110, the memory 114, and other components of the compute device 102. For example, the I/O subsystem 112 may be embodied as, or otherwise include, memory controller hubs, input/output control hubs, firmware devices, communication links (i.e., point-to-point links, bus links, wires, cables, light guides, printed circuit board traces, etc.) and/or other components and subsystems to facilitate the input/output operations. In some embodiments, the I/O subsystem 112 may form a portion of a system-on-a-chip (SoC) and be incorporated, along with the processor 110, the memory 114, and other components of the compute device 102, on a single integrated circuit chip.

The data storage 120 may be embodied as any type of device or devices configured for short-term or long-term storage of data such as, for example, memory devices and circuits, memory cards, hard disk drives, solid-state drives, or other data storage devices. Illustratively, the data storage 120 includes an audio library 130 and a video library 132 stored therein. The audio library 130 may store audio useable by the compute device 102 to generate the media compilation. Illustratively, the audio stored in the audio library is embodied as one or more digital songs, but may include other audio data (e.g., sound effects, sound bites, background noise, recorded audio, etc.). Similar to the audio library 130, the video library 132 stores one or more videos usable by the compute device 102 to generate the media compilation. The videos stored in the video library 132 may be embodied as any type of video to which a digital song or other audio may be synced including, but not limited to, a home video or other video captured by a user of the compute device 102. The videos may or may not include associated sound (e.g., the videos may be embodied as multi-media videos or A/V media).

The communication circuit 122 may be embodied as any type of communication circuit, device, or collection thereof, capable of enabling communications between the compute device 102 and other remote devices, such as the mobile compute device 104, over the network 106. The communication circuit 126 may be configured to use any one or more communication technologies (e.g., wireless or wired communications) and associated protocols (e.g., Ethernet, Bluetooth®, Wi-Fi®, WiMAX, LTE, 5G, etc.) to effect such communication.

The output devices 124 may include as any type of output device useable by the compute device 102 to present the compiled media to a user of the compute device 102. In the illustrative embodiment, the output devices 124 include a display 140 and a speaker 142, but may include additional or other components in other embodiments. The display 140 may be embodied as any type of display capable of display the compiled media to the user. For example, the display 140 may be embodied as a liquid crystal display (LCD), a light emitting diode (LED) display, a cathode ray tube (CRT) display, a plasma display, and/or other display device. Additionally, in some embodiments, the display 140 may be embodied as a touchscreen display. The speaker 142 may be embodied as any type of audio generation device, such as a speaker or annunciator, capable of playing audio of the compiled media to the user.

In some embodiments, the compute device 102 may also include one or more input devices to generate a video and/or audio, which may be subsequently used by the compute device 102 to generate the media compilation. For example, the compute device 102 may include a camera 150 configured to generate video data and/or a microphone 152 configured to generate audio data. Additionally, the compute device 102 may include other peripheral devices 154 in some embodiments.

In some embodiments, the compute device 102 may receive the video to be used to generate the media completion from the mobile compute device 104. The mobile compute device 104 may be embodied as any type of mobile computing device capable of generating a video. For example, the mobile compute device 104 may be embodied as a worn or user-carried compute device such as a pair of smart glasses, smart clothing, smart phone, a head or body-worn camera, or the like. As such, the mobile compute device 104 may include components, such as a processor and memory, typically found in a compute device. Additionally, the compute device 102 may include a camera 160 configured to generate a video of the user or of a surrounding environment of the user (e.g., a video of an activity performed by the user such skinning or skydiving). In some embodiments, the compute device 102 may also include one or more context sensors to generate context data indicative of a context of the video captured by the camera 160. For example, in the illustrative embodiment, the mobile compute device 104 includes a motion sensor 162 to capture motion data contemporaneously with the capturing of the video by the camera 160. Such motion data may be used by the compute device 102 while analyzing the video to generate the metadata of the video as discussed in more detail below. Of course, the mobile compute device 104 may include other types of context sensors and the context data associated with any captured video may include other types of context data in other embodiments.

As discussed above, the mobile compute device 104 may transmit any captured video, and associated context data, to the compute device 102 over the network 106. The network 106 may be embodied as any type of communication network capable of facilitating communication between the mobile compute device 104 and the compute device 102. As such, the network 106 may include one or more networks, routers, switches, computers, and/or other intervening devices. For example, the network 106 may be embodied as or otherwise include one or more local or wide area networks, cellular networks, publicly available global networks (e.g., the Internet), an ad hoc network, a short-range communication network or link, or any combination thereof.

Referring now to FIG. 2, in use, the compute device 102 establishes an environment 200 for generating a media compilation. The illustrative environment 200 includes an audio analysis module 202, a video analysis module 204, a media correlation module 206, a correlation prioritization module 208, a media generation module 210, and a user interface module 212. The various modules of the environment 200 may be embodied as hardware, software, firmware, or a combination thereof. For example, the various modules, logic, and other components of the environment 200 may form a portion of, or otherwise be established by, the processor 110 or other hardware components of the compute device 102. As such, in some embodiments, one or more of the modules of the environment 200 may be embodied as circuitry or collection of electrical devices (e.g., an audio analysis circuitry 202, a video analysis circuitry 204, a media correlation circuitry 206, a correlation prioritization circuitry 208, a media generation circuitry 210, and a user interface circuitry 212). It should be appreciated that, in such embodiments, one or more of the audio analysis circuitry 202, the video analysis circuitry 204, the media correlation circuitry 206, the correlation prioritization circuitry 208, the media generation circuitry 210, and/or the user interface circuitry 212 may form a portion of one or more of the processor 110, the I/O subsystem 112, the memory 114, the data storage 120, the communication circuitry 122, and/or the output devices 124. Additionally, in some embodiments, one or more of the illustrative modules may form a portion of another module and/or one or more of the illustrative modules may be independent of one another.

The audio analysis module 202 is configured to analyze one or more digital songs or other audio data stored in the audio library 130 and generate, via an audio metadata generation module 220, audio metadata indicative of one or more characteristics of each digital song. To do so, the audio analysis module 202 may analyze any aspect of the digital song including the audio content (e.g., the lyrics, tempo, melody, breaks, instruments, etc.). Additionally, in some embodiments, the audio analysis module 202 may analyze other data associated with the digital song, which may be attached to the digital song or available from a remote source. The other associated data may include, for example, metadata about the digital song such as the song genre, the song performer, the date of publication of the song, the meaning of the song, and/or other data that may not be obtainable based on a direct analysis of the content of the song.

As discussed above, the metadata generated by the audio metadata generation module 220 is illustratively embodied as one or more metadata tags. Each metadata tag may be indicative of a characteristic of the associated digital song. For example, one metadata tag may identify a lyric of the digital song (e.g., “happy birthday”), another metadata tag may identify the tempo of the digital song (e.g., “fast tempo), and yet another metadata tag may identify an object mentioned in the digital song (e.g., “birthday cake”). In some embodiments, the audio metadata generation module 220 is also configured to determine metadata location data that identifies a location within the digital song at which each metadata tag is located. For example, a metadata tag identifying an object mentioned in the digital song may include metadata location data that identifies the point in time of the digital song at which the object is mentioned. Of course, some metadata tags may not include metadata location data because such location data is inapplicable or applies to the entire digital song (e.g., a metadata tag identifying a performer of the digital song).

Similar to the audio analysis module 202, the video analysis module 204 is configured to analyze one or more videos stored in the video library 132 and generate, via a video metadata generation module 230, video metadata indicative of one or more characteristics of the corresponding video. To do so, the video analysis module 204 may analyze any aspect of the video including the video content (e.g., images of the video, objects shown in the video, actions performed in the video, colors shown in the video, motion of the video, etc.). Additionally, in some embodiments, the video analysis module 204 may include a video context analysis module 232 configured to analyze a context of the video to generate the metadata. For example, in some embodiments, the video context analysis module 232 may be configured to infer various context characteristics about the video based an analysis of the video (e.g., the video is about skiing, the video is a birthday video, etc.). Additionally, the video context analysis module 232 may analyze existing metadata attached to or associated with the video. For example, the video may include existing data associated therewith that identifies the location or time at which the video was captured. Additionally, as discussed above, the video may include context data indicative of a context of the video (e.g., as captured by the mobile compute device 104). In such embodiments, the video context analysis module 232 may analyze the context data of the video, which may be indicative of a motion of a person captured in the video and/or the videographer.

The metadata generated by the video metadata generation module 230 is illustratively embodied as one or more metadata tags. Each metadata tag may be indicative of a characteristic of the video. For example, one metadata tag may identify an image shown in the video (e.g., a birthday cake) or an action performed by a person captured in the video (e.g., person skiing). Similar to the audio metadata generation module 220, the video metadata generation module 230 may also be configured to determine metadata location data that identifies a location within the video at which each metadata tag is located. For example, a metadata tag identifying an object shown in the video may include metadata location data that identifies the point in time in the video at which the object is mentioned. Of course, some metadata tags may not include metadata location data because such location data is inapplicable or applies to the entire digital song (e.g., the location at which the video was captured).

The media correlation module 206 is configured to analyze the video metadata associated with the video and the audio metadata associated with each digital song of the audio library 130 to determine whether any of the metadata matches. To do so, the media correlation module 206 includes a metadata analysis module 240 configured to compare the metadata tags of the video metadata and the metadata tags of the audio metadata to determine whether any of the metadata tags match. The media correlation module 206 may use any suitable mechanism to determine whether a metadata tag of the video metadata matches a metadata tag of the audio metadata. For example, in the illustrative embodiment, the media correlation module 206 is configured to determine whether the characteristics identified by each metadata tag are similar to each other.

The media correlation module 206 also includes a sync point generation module 242 configured to generate a sync point for each pair of matching metadata tags. As such, each sync point is indicative of a similar characteristic between the video and one of the digital songs.

The correlation prioritization module 208 is configured to prioritize the various sync points generated by the sync point generation module 242 based on a correlation policy stored in a correlation policy database 270. To do so, the correlation prioritization module 208 includes a sync point weighting module configured to apply a weighting factor to each sync point based on the correlation policy. The correlation policy defines one or more weighting factors (e.g., numerical numbers) for each particular matching characteristic. For example, an illustrative correlation policy 700 is shown in FIG. 7. The correlation policy 700 includes a column of matching metadata (e.g., the similar characteristic defined by the matching metadata) and a row of associated correlation weighting factors. As shown, different matching characteristics have different weighting factors. For example, if a metadata tag of the audio metadata indicates a lyric that matches an image of the video defined by a corresponding metadata tag of the video metadata, the match (i.e., the corresponding sync point) between the metatag tags/characteristics is illustratively applied a weighting factor of 8 as shown in the first row of the correlation policy 700. Conversely if the lyric identified by the metadata tag of the audio metadata matches a color defined by a metadata tag of the video metadata, the match (i.e., the corresponding sync point) is applied a weighting factor of 4 as shown in the six row of the correlation policy 700. In this way, the correlation prioritization module 208 may prioritize or rank each sync point based on the correlation policy 700.

The media generation module 210 is configured to generate the media compilation using the video and one or more digital songs selected based on the sync points generated by the media correlation module 206. To do so, the media generation module 210 includes a media selection module 260 configured to select one or more digital songs based on the sync points, which identify matching characteristics between the digital songs and the video as discussed above. For example, in the illustrative embodiment, the media generation module 210 is configured to select the one or more digital songs based on the weighting factor applied to each sync song (e.g., the media generation module 210 may select the song or songs having the highest or “best” weighting factor). It should be appreciated that such selection process may occur without direction from the user of the compute device 102.

The media generation module 210 also includes a media rendering module 262 configured to compile the video and the one or more digital songs selected by the media selection module 260. To do so, the media generation module 210 may sync the selected digital song(s) with the video using the determined sync points between the digital song and video. For example, the media generation module 210 may sync the digital song to the video based on the metadata location data associated with each metadata tag defining a sync point between the video and the digital song. In this way, the media generation module 210 may time the song relative to the video for added emphasis or correlation. Additionally, in some embodiments, the media rendering module 262 may be configured to modify the audio to fit the video. For example, the media rendering module 262 may stretch or condensing the digital song (e.g., by speeding up or slowing down portions of the song).

The user interface module 212 is configured to present the media compilation to the user of the compute device 102. For example, the user interface module 212 may display the video portion of the media compilation on the display 140 and play the audio portion of the media compilation on the speaker 142. Additionally, the user interface module 212 may provide an interface through which a user of the compute device 102 may modify or adjust the media compilation. For example, should the user not like the selected digital song(s), the user may modify such selection and cause the compute device 102 to re-render the media compilation with a different digital song.

Referring now to FIG. 3, in use, the compute device 102 may execute a method 300 for analyzing audio to generate audio metadata associated with the audio. As discussed above, the audio is embodied as one or more digital songs in the illustrative embodiment, but may be embodied as other types of audio data in other embodiments. The method 300 begins with block 302 in which the compute device 102 determines whether to generate audio metadata. For example, the compute device 102 may be configured to periodically generate audio metadata for songs stored in the audio library 130 or to generate such audio metadata in response to a user instruction. Regardless, if the compute device 102 determines to generate the audio metadata, the method 300 advances to block 304 in which the compute device 102 obtains the audio to be analyzed. As discussed above, the compute device 102 may retrieve one or more digital songs from the audio library 130 in block 306. Additionally, in some embodiments, the compute device 102 may receive one or more digital songs or other audio from a remote device (e.g., from the mobile compute device 104) in block 308.

After the compute device 102 has obtained the audio to be analyzed, the method 300 advances to block 310 in which the compute node analyzes the digital song or other audio to determine audio metadata. To do so, as discussed above, the compute device 102 may analyze the audio content in block 312 (e.g., the lyrics, tempo, melody, breaks, instruments, etc.). Additionally, in block 314, the compute device 102 may analyze additional data, such as metadata attached to the digital song and/or obtainable from a remote source (e.g., the song gene, the song performer, etc.).

Subsequently, in block 316, the compute device 102 generates the audio metadata based on the analysis of the audio performed in block 310. As discussed above, the audio metadata defines one or more characteristic of the corresponding digital song or other audio data. For example, in block 318, the compute device 102 may generate one or more metadata tags, each of which defines a corresponding characteristic of the digital song or other audio data (e.g., a specific lyric, the song genre, the song temp, etc.). Additionally, in block 320, the compute device may generate metadata location data for one or more of the metadata tags. As discussed above, the metadata location data identifies a location (e.g., a temporal location) in the digital song or other audio data at which the characteristic defined by the associated metadata tag is located.

After the compute device 102 has generated the audio metadata for the analyzed audio, the method 300 advances to block 322 in which the compute device 102 stores the metadata in the audio library 130. For example, as shown in block 324, the compute device 102 may store the metadata in association with the corresponding digital song or other audio data. The method 300 subsequently loops back to block 302 in which the compute device 102 determines whether to generate audio metadata for another digital song or other audio data.

Referring now to FIG. 4, in use, the compute device 102 may execute a method 400 for analyzing a video to generate video metadata associated with the video. The method 400 begins with block 402 in which the compute device 102 determines whether to generate video metadata. For example, the compute device 102 may be configured to periodically generate video metadata for videos stored in the video library 132 or to generate such video metadata in response to a user instruction. Regardless, if the compute device 102 determines to generate the video metadata, the method 400 advances to block 404 in which the compute device 102 obtains the video to be analyzed. For example, in block 406, the compute device 102 may retrieve the video from the video library 132 (e.g., in response to a selection from the user). Additionally or alternatively, the compute device 102 may receive the video from a remote device in block 408. For example, as discussed above, the compute device 102 may receive a video from the mobile compute device 104 via the network 106 in block 408. Additionally, in some embodiments, the compute device 102 may receive context data associated with the video in block 410. As discussed above, the context data may be indicative of any context of the video.

After the compute device 102 has obtained the video to be analyzed, the method 400 advances to block 412 in which the compute node analyzes the video to determine video metadata. To do so, as discussed above, the compute device 102 may analyze the video content in block 414 (e.g., images of the video, objects shown in the video, actions performed in the video, colors shown in the video, motion of the video, etc.). Additionally, in block 416, the compute device 102 may analyze additional data, such as metadata attached to the video (e.g., the location at which the video was captured). Further, in block 418, the compute device 102 may analyze any context data associated with the video. For example, as discussed above, the context data may include motion data of a person captured in the video and/or the videographer. As such, the compute device 102 may analyze such motion data to determine the video metadata (e.g., what activity a person captured in the video is performing).

Subsequently, in block 420, the compute device 102 generates the video metadata based on the analysis of the video performed in block 412. As discussed above, the video metadata defines one or more characteristic of the video. For example, in block 422, the compute device 102 may generate one or more metadata tags, each of which defines a corresponding characteristic of the video (e.g., an image shown in the video, a phrase spoken in the video, a color shown in the video, etc.). Additionally, in block 424, the compute device 102 may generate metadata location data for one or more of the metadata tags. As discussed above, the metadata location data identifies a location (e.g., a temporal location) in the video at which the characteristic defined by the associated metadata tag is located.

After the compute device 102 has generated the video metadata for the analyzed video, the method 400 advances to block 422 in which the compute device 102 stores the metadata in the video library 132. For example, as shown in block 428, the compute device 102 may store the metadata in association with the corresponding video. The method 400 subsequently loops back to block 402 in which the compute device 102 determines whether to generate video metadata for another video.

Referring now to FIGS. 5 and 6, in use, the compute device 102 may execute a method 500 for generating a media compilation. The method 500 beings with block 502 in which the compute device 102 determines whether to generate a media compilation. If so, the method 500 advance to block 504 in which the compute node selects the video to be included in the media compilation. For example, in some embodiments, the user of the compute device 102 may instruct the compute device 102 which video to use for the media compilation via the user interface module 212. Subsequently, in block 506, the compute device 102 retrieves the selected video from the video library 132. Additionally, in block 508, the compute device 102 retrieves the video metadata associated with the video form the video library 132. As discussed above, the video metadata includes one or more metadata tags that each defines a different characteristic of the video.

In block 510, the compute device 102 compares the metadata of the selected video with the metadata associated with each digital song (or other audio data) stored in the audio library 130. To do so, the compute device 102 may compare each metadata tag of the video metadata to each metadata tag of the audio metadata of each digital song. In some embodiments, the compute device 102 may reduce the pool size of available digitals songs to analyze in block 512. For example, a user of the compute device 102 may instruct the compute device 102 to ignore some digital songs or only use a subset of digital songs from the audio library 130.

In block 514, the compute device 102 correlates the video metadata of the selected video and the audio metadata of one or more digital songs based on the whether the characteristics defined by the corresponding metadata are similar. For example, in block 516, the compute device 102 may determine whether a metadata tag of the video metadata matches one or more metadata tag of the audio metadata associated with one or more digitals songs. To do so, the compute device 102 may determine whether the characteristics identifies by each pair of metadata tags are similar. As discussed above, the compute device 102 may utilize any suitable methodology to determine whether the pair of metadata tags and/or associated characteristics is similar to each other.

For each matching pair of metadata tags (i.e., a metadata tag of the video metadata and a metadata tag of the audio metadata), the compute device 102 generates a sync point between the video and corresponding digital song or other audio data. As discussed above, each sync point is indicative of a similar characteristic between the video and the corresponding digital song. The compute device 102 may generate any number of sync points based on the number of similar or matching characteristics between the video and the corresponding digital song.

After the sync points have been generated in block 518, the method 500 advances to block 520 in which the compute device 102 prioritizes the generated sync nodes. For example, in block 522, the compute device 102 may apply a weighting factor to each sync point based on the correlation policy (e.g., the correlation policy 700 shown in FIG. 7). As described above, the correlation policy defines one or more weighting factors (e.g., numerical numbers) for each particular matching characteristic. As such, the compute device 102 may be configured to prioritize the sync nodes based on the weighting factors identified in the correlation policy.

After the compute device 102 has prioritized each sync node, the method 500 advances to block 524 of FIG. 6. In block 524, in some embodiments, the compute device 102 may present the generated sync node and associated weighting factors to the user a sync table. For example, an illustrative sync table 800 is shown in FIG. 8. The sync table 800 includes a first column 802 identify video metadata of the video, a second column 804 identify audio metadata of a digital song that matches the video metadata of the same row, and a third column 806 that identified the weighting factor applied to each matched metadata (i.e., matched characteristics). As discussed above, the weighting factors applied to each matched metadata is based on the correlation policy. Referring back to FIG. 6, in block 526, the user of the compute device 102 may update the one or more of the applied weighting factors to increase or decrease the priority of a corresponding matched metadata.

In block 528, the compute device 102 determines whether to generate a media compilation based on the selected video and the generated prioritized sync points. If so, the method 500 advances to block 530 in which the compute device 102 selects one or more digital songs or other audio to be included in the media compilation based on the prioritized sync points. For example, the compute device 102 may select those sync points having the highest or “best” corresponding weighting factors.

After the one or more digital songs or other audio data has been selected in block 530, the method 500 advances to block 532 in which the compute device 102 compiles the selected video and audio to generate the media completion. To do so, in block 534, the compute device 102 may sync the selected digital song(s) with the video based on the sync points defined between the video and corresponding digital song. For example, in block 536, the compute device 102 may sync the digital song(s) to the video based on the metadata location data associated with each metadata tag defining a sync point between the video and the digital song (e.g., to temporally match characteristics of the video and digital song). Additionally, in some embodiments, the compute device 102 may modify the audio to better fit or otherwise sync with the video. For example, the compute device 102 may stretch or condense the digital song (e.g., by speeding up or slowing down portions of the song).

After the compute device 102 has generated the media compilation in block 532, the method 500 advances to block 540 in which the compute device 102 presents the compiled media to the user of the compute node. For example, the compute device 102 may display the video portion of the media compilation on the display 140 and play the audio portion of the media compilation on the speaker 142.

In block 542, the compute device 102 determines whether the user approves the generated media compilation. For example, the user may supply a user input or instruction via the user interface module 212 indicative of whether the media compilation is acceptable to the user. If not, the method 500 advances to block 544 in which the compute device 102 may receive user modifications to the selected audio. For example, the user may remove a song from the media compilation, request that another song be added, change the relative temporal position of the song, and/or provide additional modifications to one or more digital songs of the generated media compilation. After the compute device 102 receives the user modifications, the method 300 loops back to block 532 in which the compute node re-compiles the selected video and updated digital song(s) to generate a new media compilation, which is subsequently presented to the user in block 540. If, however, the user approves the media compilation in block 542, the method 500 advances to block 546 in which the compute device saves the compiled media (e.g., in the data storage 120).

As described above, the compute device 102 is configured to generate a media compilation using a selected video and a library of digital songs or other audio data.

Additionally, in some embodiments, the compute device 102 may generate the media compilation with little or no direction from the user.
